VENTILATOR.

Specification of Letters Patent.

Patented Aug. 31, 1909.

Application filed March 25, 1909. Serial No. 485,760.

buildings and the like and the objects there-- 7 of are to provide a new and improved de-' vice of the kind specified provided with:

openings to permit the escape of air from the building or apartment arranged to be closed by dampers so constructed and arranged that they may be closed individually or simultaneously at the will of the operator of the device, thereby to a certain extent controlling the ventilation ofthe building.

Another object of the invention is to provide a roof for the ventilator comprising a' sheet of translucent material, thereby .permitting light to enter the building or apartment and yet prevent the entrance thereto of foreign matters such as rain, sleet, snow, dust and other deleterious substances.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts constituting the invention to be hereinafter specifically describedand illustrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings, in which similar reference numerals indicate like parts in the different figures: Figure 1 is a vertical sec tional view of a device embodying this invention approximately on line X ofFig. 2 and Fig. 2 is a plan of the device.

Referring to the drawings in detail, the reference numeral 1 denotes an upwardlyextending flue, preferably constructed of sheet metal arranged to be positioned in the roof or other suitable portion of an apartment or building to be ventilated. Mounted on the fine 1 is a plate 2 approximately in the general conformation of a Greek cross provided centrally with an opening adapt ed to register with the upper end of the flue 1 with a marginal downwardly-extending by solder or other equivalent means.

flange 3 arranged to be inserted in and lap the upper end of the flue 1 and be held thelil'e T e plate 2 is preferably provided with a plurality of laterally-extending arms or louvers 1 which are downwardly-bent or inclined for the purpose of forming the floors of outlets for the air carried upwardly through the fiue 1. v

Secured to the side edges of the arms 1 of the plate 2 are upwardly-extending members 5 of an approximately right-angular configuration in cross-section, the laterally-projecting portionsof which serve to form the sides of openings of which the louvers 1 form the bottom. The upper outer portions of the members 5 are preferably beveled at 6.

Mounted on the members 5 is a second plate 7 conforming in contour to the plate 2 with the arm-portions or louvers 8 thereof preferably downwardly-bent approximately -parallel with the downwardly-inclined louvers 1. The arms 8 of the plate 7 are adapted to be secured to the beveled upper edges 6 of the upwardly-extending members 5 by solder or other equivalent means. The central portion of the plate 7 is provided withan opening 9 surrounded by an upwardly-extending mar inal flange 10.

Mbunted on the plate 7 and lapping the marginal flange 10 is a sleeve 11, preferably cyllndrical in outline, provided with a lateral flange 12 constituting a seat for a sheet 13 of translucentmaterial. The sheet 13 of translucent material is preferably octagonal as shown in Fig. 2. Mounted on the arms or louvers 8 of the plate 7 is an octagonallyformed member 14 the lower portions of which. are provided with outwardly-bent portions 15 secured by suitable holdfast devices 16 to the upper face of the arms 8 of the member 7 The side portions of the member 1 1 are provided with a plurality of semi-circularly-shaped openings 17 formed by. semi-circular cuts, the material 18 inclosed by said cuts being bent inwardly wardly and-downwardly with their lower portions resting on the plate'2 at the line where the inclined louvers l thereof commence. Thev lowerportions of these dampers 19' are preferably downwardly-turned so as to encounter the upper surface ofthe' plate 2 accurately and form therewith a r is " levers 23 is employed tor operating them. It

will be obvious that in place of limiting the" ton-r branches 26 into a eonmion cord 25, whereby all the levers will be tilted at once,

7 each individual lever may bepreovided with a separatecord so that each may be operated individually.

The lower end .of each of; the dampers 19 is provided with a slotted opening 31 to permit the passage therethrough of one of the levers 23 without interfering with the operation of the damper 19."" EXtending bet-ween the contiguous .outer faees of the plates hare braces 27 each provided with a beveled portion 28 adapted to support a wind-shield 29 secured on the braces through the medium of holdfast devicesBO. in operation, when it is desired to open the ventilator to permit the air in the building or apartment to escape, the cord is drawn downwardly which tilts all the levers simultaneously into the position shown by one of them dotted lines in Fig. 1. As

the inner end of each lever is pulled downwardly by the rope 25 the upper end of the lever 23 raises the link 22 and swings the I damper 19 .on itspivot pin 20v into the posi-- tion shown by the dotted lines and substantially. into abutting relation with the inclinedlouver 8 of the member 7 immediately' above it, leaving the space between the louvers 8. and 4 open to constitute an outlet for the passage therethrough of the air from the building or apartment. A reversal of this operat-ion'will close either one or allofthe dampers, as desired;

' Itwill be noted that foreign matter such as. rain, snow and sleet will be deflected away from the outlet opening by means of the inclined arms 8 of the member 7 and any foreign matter which lodges on the inclined arms 4 will be deflected thereby to the roof of the apartment or building in connection with whichthe device is used.

Itwill be seen that the sheet of trans-' 'l-ucent-material 13 constitutes a roof for the ventilator and at the same time permits the entrance of light to the interior of the flue and from thence to the apartment or building in which the latter is used, and any considerable deposit of water on this sheet of translucent material is permitted to escape through the openings 17 in the member 14: from whence it passes to the roof outside of the Ventilator.

What I claim and desire to secure by Letters Patent, is
